r'lhisinvention relates toan improvedcon Incoy Figure lis asectional edgeviewof door in closed position'showing the `construction of door fastening Inechanisni more particularly adapted for use on vehicle doors, .such as automohilesa'nd the like; and the object of this inventionnis `tofprovidea door-fastening mechanism such as aA latch and the'like ,which .is mounted to wedge-be tweenftheedgfe of the .door and the Ydoor jainh portion to hold theY door ,closed and at the same timebind the door securely against rattling. o

1A further objectief the invention isfto'provde converginghinding plates on the 5 door amb and on the' door 'and vto providefja 4loclsi v'roll Qrother'member which is adapted to e moved to wedge between these conind the same 'against rattling,
